Calciphylaxis: an uncommon manifestation of primary hyperparathyroidism. A case report.

Calciphylaxis is a rare disorder which mainly affects patients with end-stage renal disease and secondary hyperparathyroidism. We report here a case of calciphylaxis in a 56-year-old woman with primary hyperparathyroidism, a much more uncommon association. Skin biopsy revealed the characteristic pictures of the disease. Soon after parathyroidectomy, the parameters of the phosphorus-calcium metabolism normalised but the cutaneous lesions persisted for several months.
